Mary anne sold 20 necklaces and bracelets at the craft fair. she sold 3 times as many necklaces ad bracelets. how many bracelets and necklaces did mary anne sell?

The number of necklaces and bracelets that mary anne sold are;

15 necklaces and 5 bracelets

We are told that;

Number of necklaces and bracelets sold = 20

Let number of necklaces be x and let number of bracelets be y.

Thus;

x + y = 20

We are told that she sold 3 times as many necklaces as bracelets. This means that; x = 3y

Putting 3y for x in x + y = 20 and we have;

3y + y = 20

4y = 20

divide both sides by 4 to obtain;

y = 20/4

y = 5 bracelets

Since x + y = 20, then;

x + 5 = 20

x = 20 - 5

x = 15 necklaces

Thus, she sold 15 necklaces and 5 bracelets
